MACHINE FOR CUTTING OUT FELLIES.

Specification of Letters Patent No. 6,521, dated June 12, 1849.

T0 all whom z't may Concern Be it known that we, JOSEPH ADAMS, LEVIADAMS, of Hadley, Hampshire-county, and State of Massachusetts, andLUTHER H. MOORE, of Leverett, county of Franklin and State ofMassachusetts, have invented a new and useful Improvement in Machine forCutting Fellies for Wheels, which is described as follows, referencebeing had to the annexed drawings of the same, making part of thisspecification.

Figure l is a vertical longitudinal section vof the machine at the linem of Fig. 2.

Fig. 2, is a top or birds-eye view of ditto, with the friction wheels orpulleys removed, their relative positions being represented by dottedlines. Fig. 3, is an elevation of the Fig. 4, is a side view of thelever or treadle for clamping the timbers from'which the fellies arecut.

Similar letters in the figures refer to corresponding parts.

The nature of this invention and improvement consists in securing to theupper end of a vertical shaft turning in boxes in a suit-able frame, ahorizontal beam having adjustable cutters attached near its extremitiesat the required relative distance from the center of the shaft tocorrespond with the inner and outer curvative of the felly to be cut andcausing said cutters to revolve over the timber fro-m which the felliesare to be cut, and gradually descend during their revolutions by meansof bands, pulleys, friction wheels, screw shaft, levers, &c.; and cutthe felly, and by means of the movementof a lever to reverse themovement of the screw shaft, and cause the cutters to ascend to theiroriginal positions to allow the operator to bring the timber forward foranother cut.

To enable persons skilled in the art to make and use our invention wewill proceed to describe its construction and operation.

A is the frame 'made of suitable size strength and material to containand support the several parts for which it is designed.

B is an upright shaft, resting in a movable step at its lower end, andhaving a horizontal circular plate a, secured to its upper end,immediately below which is formed a hub b turning in a correspondingsized bo-x, for st-eadying the upper end of the axle during itsrevolution.

C is a horizontal beam secured betweenl projections formed on the uppersurface of ythe circular plate. l D are angular metallic boxes havingflanges on their sides, and secured to near the extremities of the beam,on opposite sides of the same, by means of oblong iron straps c passingaround the beam and pressed against said flanges by screws d,

passing through female screws in the straps and resting, against oblongplates on the sides of the beam, opposite the boxes, in such a manner asto allow of the boxes being moved either farther from or nearer to thejupright shaft to accommodate them to the justed by screws e.

F is an upright shaft resting in a. step 4in the frame, and turning in abox secured to a vibrating beam or timber at it-s upper end and providedwith a friction wheel or pulley f' at top and a series of unequal sizedpulleys g below around one of which is passed a band l1, leading arounda pulley z' on the vertical shaft B.

G is a lever having a step on its upper surface in which the shaft Brests, arranged below the frame and secured at one end to the front partof the same by a pin upon which it moves, and resting at its oppositeend upon a similar lever j placed at right angles to the same, moving ona pin at one end, and connected to a cross head 7c moving betweenupright slides-or ways at the opposite end by a connecting rod Z, ironstraps m, and oblong plates.

H is a vertical screw shaft passing through a female screw formed in thecross head, being rounded at its lower end, which turns in acorresponding formed opening or step, formed in a permanent iron blockn, secured to the frame and supported near its upper end by a suitablebox in the frame, and provided with a friction wheel or pulley 0 ofsmaller diameter than the wheel f, from which it derives its motionduring the ascent of the cross head and parts attached.

I is an upright shaft resting in a step at its lower end, and turning ina box secured to a vibrating timber or beam above, and provided at topwith a friction wheel or pulley p of smaller diameter than the last 'theend of the lever j, below the frame, andv having a weightt, suspended onits opposite end of suiiicient gravity to counterbalance the weight ofthe vertical shaft of cutters, and levers Gr, y', combined, and thusrelieve the screw 0f part of the pressure bearing on the same, andprevent its too sudden wear.

K is the horizontal beam containing the boXes in which the upper ends ofthe upright shafts F, I, turn, resting on the upper horizontal timber ofthe frame and provided with tenons at each end which are insertedloosely into correspnding formed mortises, in the vertical posts of theframe and having cords attached to its ends, one of which u, passes overa pulley on one side of the frame, and sustains aV weight e, while theother passes over a similar pulley on the opposite side, and is attachedto a lever w arranged on the side of an upright post, and moving on afulcrum at one end in such a manner that by lowering said lever, thecross head containing the female screw, and the several parts attachedto the same will be caused to ascend, and by raising the same, l

the weight will cause the friction wheels or pulleys to so engagetogether as to reverse the motion of the screw and force the cross head,&c., down.

Operation: When it is desired to cut a felly with this machine, thetimber from which itis to be cut is placed on the table and is firmlysecured by placing one end against the dog and clamping the opposite endby pressing it between the clamp and table, and the cutters are adjustedin such relative positions to each other, as to cause one to pass overthe timber, in its revolution, outside the curvature of the intendedfelly, and the other 0n the inside curve of the same. Motion is thencommunicated to the machine by any convenient power, and the to belowthe pin 2, which will cause the W beam K and friction pulleys f, p, tobe drawn back to their original positions, and the two larger pulleys f,o, to engage, and the motion of the screw to be reversed, so as to raisethe cross head and its attachments, together with the vertical shaft ofcutters, t0 the point from which they started, when the motion ofthermachine is stopped, and the timber brought forward for another cut.In this manner the operation, is continued.

When it is desired to cut a larger sized felly, the dog and clamp may beplaced in the openings in the table corresponding with the size wanted,and the cutters moved on the beam to adapt them to the purpose.

What we claim as our invention and desire to secure by Letters Patentis- The combination of the cutter-head and beam O, with the levers G, j;cross head c moving between upright slides and attached to the lever y'.by the connecting rod Z, iron straps m, and oblong plate; screw shaftH, passing through the cross-head, and provided with the friction wheelo, which is alternately thrown into gear with the fric.

tion wheels f, p, on the upper ends of the shafts F, I, by means of thehorizontal beam-
